Somebody's been giving questionable advice...
Headphones won't cause a song to skip. They only play what comes out of the device.
Seriously though...before I got the Skullcandy's with the gold-plated jack, the skipping was so bad, I couldn't even listen to it. It was like the fast-forward button was constantly being pushed. I read on the Eris forum about switching buds. After the switch, the songs only skipped for a couple of seconds in the beginning. I even bought a holster because I was just keeping the phone in my pocket while gardening. Old headphones still skipped even in the holster, Skullcandy's only skipped during first few seconds of each song. Luckily, I only payed $5 for the Skulls because my hubby had a BB reward certificate that was expiring, so he gave it too me! And I like the way the fit in my ears better than my cheap Sony's. And, I got rid of my Eris...and my order for the DI has been processed, so my new phone is on it's way!!!
So I guess it doesn't matter any more anyway! LOL
